I haven't used it much, so I think it's in good condition. This is a Smart Kids Belt from Meteo APAC Co., Ltd. I am selling it because my child has outgrown it. It is a used item, so there is no box, only the item itself. Please be aware of this. The buckle is quite stiff. Please check the following Meteo website for usage instructions and how to identify genuine products: https://www.meteorapac.jp/smartkidsbelt/
